DRILLING- MACHINE.

Application filed Dec mber 29, 1924. Serial No, 753,749.

To all whom it may concern:

Be it known that I, Mason GILBERT CAR- rnNrnR, a citizen of the United States, residing at Marietta, in the county of Washington and State of Ohio, have invented a new and useful Drilling Machine, of which the following is a specification.

This invention aims to provide, in a machine of the sort above mentioned, a novel drive for the cable spool and the calf wheel, to provide apumping mechanism of novel form, to improve the construction and operation of the sand line reel, to improve the spudding mechanism, and, generally, to improve and enhance the utility of devices of that sort to which the invention appertains.

Although a preferred form has been shown, it will be understood that a mechanic, working within the scope of what is claimed, may make such alterations as his skill may suggest, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the inven tion, the parts being in the positions which they will assume when the spudding operation is being carried out;

Figure 2 is a top plan wherein parts are broken away;

Figure 3 is a longitudinal section wherein parts are omitted Figure 1 is a side elevation wherein the walking beam is shown coupled up with its driving mechanism, parts being broken away; and

Figure 5 is a sectional detail, showing in elevation, a portion of the pumping mechanism.

The device forming the subject matter of this application comprises a wheel-mounted frame 1 provided at its forward end with a standard 2 to which a mast 3 is pivoted at 1, so that the mast can be folded backwardly into an out of the way position, if desired, although a foldable mast is not insisted upon. The lower end of the mast 3 is connected to the standard 2 by a securing member 5, and the mast is sustained by guys 6. The mast 3 carries an upper pulley 7 and a lower pulley 8.

An engine 9 is mounted on the end of the frame 1, and may be of any desired construction. The engine 9 drives a shaft 10 journaled on the frame 1 and disposed transversely of the frame, the shaft 10 carrying a pulley 11 about which is engaged a belt 12 cooperating with a larger pulley 1 1 on a shaft 15 disposed transversely of the frame 1 and journaled thereon. The shafts 10 and 15 may be connected at their outer ends by a brace 16.

The shaft 15 carries a friction wheel 17. located inside the frame 1, the friction wheel 17 being adapted to cooperate with a friction wheel 18 on a shaft 19 carrying the sand line reel 20, one end of the shaft 19 being journaled in a bearing 21 on one side of the frame 1, and the-other end of the shaft being journaled shiftably in a bearing 22 on the opposite side of the frame, the frame carrying a brake 23, and it being possible to shift the friction wheel 18 into and out of engagement with the friction wheel 17, and into andout of engagement with the brake 23. The mechanism for shifting the shaft 19 in the bearing 22 to cause the friction wheel 18 to cooperate with the friction wheel 17 or with the brake 23, embodies an operating member in the form of a rod 24:, slidable in a support 25 on the forward end of the frame 1. The sand line, proceeding from the reel 20, over the pulley 8, is marked by the numeral 26.

A shaft 27 extends transversely of the frame 1, the shaft being j ournaled in a bearing 28, on one side of the frame, and being shiftably journaled in a bearing 29 on the opposite side of the frame, the shaft 27 carrying a friction wheel 30, located within the frame 1, andadapted to be brought into contact with the friction wheel 17, or into contact with a brake 31 on the frame 1. The means: for imparting movement to the shaft 27, thereby, to cause the friction wheel 30 to cooperate either with the brake 31 or with the "friction wheel 17 comprises an operating member 32, in the form of a rod, extended to the forward end of the frame 1 and slidably supported on the frame.

A shaft 33 is journaled on the frame 1, below and slightly in advance of the shaft 27, the shaft 33 carrying a gear wheel 34. A pinion 35 is splined to the shaft 27, to slide therealong, and, through the instrumentality of the lever 36, extended to the forward end of the frame 1, and fulcrumed intermediate its ends thereof, as shown at 37, the pinion 35 may be shifted into and out of mesh with the gear wheel 34. About shaft 83 is wound. a casing line 38 which is by the shaft 10, the-pulley 11, the belt 12,'

exten-ded over the lower pulley S on the mast 3.

The pinion on the shaft 27 may be shifted into and out; of mesh with a gear wheel 39 on a shaft 40 journaled on the frame 1, the gear wheel 39 and an end plate 41 forming a reel for the drilling line 42. One end of the shaft 40 carries a disk 43 coacting with a brake strap 44 connected to an arm 45 on a shaft 46 mounted to rock in one side of the" frame 1', the shaft 46 having a depending arm 47 c'onnec'ted by a link 48 with an arm 49 on a shaft 50 mounted to rock in one side of the frame, the shaft 50 being provided with a forwardly extended handle 51 which is accessible from the forward end of the frame 1.

On the shaft 15 t'l'rer'e isan eccentric 52 cooperating with a strap 53 a pitman 54 pivoted to a radius arm mountedto swing on the frame, the radius arm 55 being connected by a link 56 to the plunger 57' of a pump 58- car'ried' by the frame of the machine and communicating with a conduit 59". The ump may be used for any purpose for which a pump is needed.

The line 42 is extended backwardly about anidler 60 on the frame, the idler being located on' the rear end of the frame, at a point near to the longitudinal'ce'nter ofthe frame. Fromthe idler 60, the line 42 extends outwardly and forwardly about a pu'lley 61 journal'e'd under a bracket 62 on the frame, the bracket terminating in a hook 63', adaptedto receive a longitudinally adjustable anchor-64'. From-the pulley 6 -1, the line 42 extends beneath vertically disposed pulley 6 5 carriedby a outwardly from the frame. The line 42 passes beneath a pulley 67 one wrist pin 68 mounted ona crank 69 carried by the shaft 15.; From thepulley 67, the line 42 is trained over the pulley 7 on the mast 3.

The drives are as follows The shaft 15 is driven from the engine 9 and the pulley 14 Assuming that the friction wheel 18 is out of engagement with the friction wheel 17, that the friction WheelBO is engaged with the wheel 17, and that the pinion 35 is engaged neither with" the gear wheel 39 nor with the gear wl'ieel $4, it-will be obvious that, when tl'1e shaft'15 is rotated, the crank 69 and the pulley 67 will operate the line 42 in the necessaryway to carry out the spudding' operation.

The line 42 may be cast off thepulley 67, and, if the pinion 35 is engaged with the gear wheel 39, the shaft 40 will be rotated on the shaft 15,- by the friction wheels 17 and 30, andby the gear elements-35and 39, so that the line 42 will he reeldOn the shaft" 40. I i

It isebvious that, if desired, the friction wheel 18 may he brought into cooperation bracket 66 extending with the friction wheel 17, thereby operating the shaft 19 toreel in or out the sand line 26.

Thesa-mson post is marked by the numeral 70, and the walking beam 71, fulcrunred' on the samson post, is denoted by the numeral 71, a Walking beam being connected by a pitman 72 with the crank pin 68 on the crank 69 of the shaft 15. This set up is shown in Figure 4, whereas Figure 1 shows how the parts are arranged whilst the spudding' operation is being carried out. Y I
